+This release adds support for four more languages, reduces the memory footprint under some circumstances and enables a few more emulators.
 
-On Android the default audio driver has been changed from AAudio to OpenSL ES which should decrease audio latency on many devices. There's also a new menu option in the Sound settings menu that makes it possible to easily revert to AAudio in case of issues with using OpenSL ES. For Android there is now also experimental support for running ES-DE in multi-window mode on tablets and other devices that support this.
